SENA series are manually operated metallic ball valves that by its design and raw materials are intended to be used in:

Drinking water networks.Water supply connection.Plumbing networksHot water networks.Heating systems.

In general all those applications where it is required a valve to stop the fluid supply, assuring the leaktightness in accordance to the working conditions.

Nominal pressure: 30 bar Test pressure: 45 bar Temperature range: -20ºC up to120ºC, excluding frozen.Fluid: Drinking water and hot water.

MAIN CONSTUCTIVE FEATURES

Body and lateral Main body and lateral manufactured in European brass alloy CW617N, by the mean of a hot stamping process. This process confers to the European brass alloy the following advantages against casting parts:

- Pores absence.

- Surfaces with better finished and without bumpy texture.

- Higher mechanical endurance .

Seats and sealing gland Seats and sealing gland are made in PTFE, avoiding internal and external leaktighness due to its perfect fit on metallic surfaces.

Spherical closure Spherical closure is made in brass, ensuring a higher mechanical endurance against high pressure and maneuvers.

Its diamond mechanized and the following chrome plated applied on the ball surface assure a long lifespan and a smooth maneuver.

Internal leaktightness (Close position) Internal leaktightness is assured in both directions by the PTFE seat that press against the spherical closure.

External leaktightness (Open position)

External leaktighness through the stem is assured by a PTFE sealing gland allowing its retightening if necessary.

Connections

Within the series SENA can find two types of threaded fasteners. The most common is the ISO 228 although female / female threaded version junctions can find NPT (ANSI / ASME B.120.1).

HYDRAULIC FEATURES

INSTALATION AND ASSEMBLY

The SENA series has been tested by our laboratory to determine the hydraulic characteristics of flow rate vs losses to European standard EN 1267.

Hold the valve from faces of the hexagons, never from the central part or its neck, that will avoid internal components deformations (in other case valve could be damaged inevitably).

The maximum valve life is obtained with the closure sphere in the full open or close position, it is recommended do not work in intermediate positions for long time periods.

Valve must be maneuver every 3 months, this frequencies must be increased for waters with a French hardness over 50º.
